1U–Pb ages and Hf isotopes for detrital zircons from quartzite in the Paleoproterozoic Songshan Group on the southwestern margin of the North China Craton显示文摘In situ U-Pb dating and Lu-Hf isotopic analysis were carried out for detrital zircons from quartzite in the Paleoproterozoic Songshan Group on the southern margin of the North China Craton (NCC). The re- sults provide further constraints on the crustal formation and evolution history of NCC. Four 207Pb/206Pb age populations were obtained from 99 analyses, with clusters at ~3.40 Ga, 2.77―2.80 Ga, ~2.50 Ga and 2.34 Ga, respectively. The 3.40 Ga old zircons have similar Hf isotopic compositions to those from Ar- chean rocks in the Jidong and Anshan areas of NCC. However, crustal remnants older than 3.6 Ga have been identified in the southern margin of NCC, the South China Craton, the northwestern part of the Qinling Orogen and its adjacent area. Thus, it is not easy to trace the source rock from which the 3.40 Ga detrital zircons were derived. It can be inferred that the crustal remnants older than 3.40 Ga might have been widely distributed in the North China Craton. The 2.77―2.80 Ga zircons make up a relatively small proportion and have the highest εHf (t) values (up to 6.1±1.6), consistent with the Hf isotopic composition of the depleted mantle at 2.83 Ga. Their single-stage Hf model age of 2.83 Ga is close to their crystallized age, suggesting that their source rocks were extracted from the contemporaneous depleted mantle. The ~2.50 Ga zircon grains constitute about 85% of the total grain population and their Hf isotopic compositions indicate major growth of juvenile crust at ~2.50 Ga but minor reworking of ancient crust. The youngest zircon dated in this study gave an U-Pb age of 2337±23 Ma, which can be considered the maximum depositional age of the formation of the Songshan Group.DIWU ChunRong SUN Yong YUAN HongLin WANG HongLiang ZHONG XingPing LIU XiaoMing 2008Chinese Science Bulletin2008,53,18:54

3A telomere-to-telomere gap-free reference genome of watermelon and its mutation library provide important resources for gene discovery and breeding显示文摘Watermelon,Citrullus lanatus,is the world's third largest fruit crop.Reference genomes with gaps and a narrow genetic base hinder functional genomics and genetic improvement of watermelon.Here,we report the assembly of a telomere-to-telomere gap-free genome of the elite watermelon inbred line G42 by incorporating high-coverage and accurate long-read sequencing data with multiple assembly strategies.All 11 chromosomes have been assembled into single-contig pseudomolecules without gaps,representing the highest completeness and assembly quality to date.The G42 reference genome is 369321829 bp in length and contains 24205 predicted protein-coding genes,with all 22 telomeres and 11 centromeres characterized.Furthermore,we established a pollen-EMS mutagenesis protocol and obtained over 200000M1 seeds from G42.In a sampling pool,48 monogenic phenotypic mutations,selected from 223M1and 78 M2 mutants with morphological changes,were confirmed.The average mutation density was 1 SNP/1.69Mband1 indel/4.55 Mb per M1 plant and 1SNP/1.08Mb and 1 indel/6.25 Mb per M2 plant.Taking advantage of the gap-free G42 genome,8039 mutations from 32 plants sampled from M1 and M2 families were identified with 100%accuracy,whereas only 25% of the randomly selected mutations identified using the 97103v2 reference genome could be confirmed.Using this library and the gap-free genome,two genes responsible for elongated fruit shape and male sterility(CiMs1)were identified,both caused by a single basechange from G to A.The validated gap-free genome and its EMS mutation library provide invaluable resources for functional genomics and genetic improvement of watermelon.Yun Deng Shoucheng Liu Yilin Zhang Jingsheng Tan Xiaopeng Li Xiao Chu Binghua Xu Yao Tian Yudong Sun Bosheng Li YunbiXu Xing Wang Deng Hang He Xingping Zhang 2022Molecular Plant2022,15,8:9
4Preparation and Mechanical Properties of-SiC Nanoparticle Reinforced Aluminum Matrix Composite by a Multi-step Powder Metallurgy Process显示文摘β-SiC nanoparticle reinforced Al matrix(nano-SiCp/Al) composite was prepared by a multi- step powder metallurgy strategy including presureless sintering, hot compacting process and hot extrusion. The microstructures of the as-prepared composites were observed by scanning electronic microscopy(SEM), and the mechanical properties were characterized by tensile strength measurement and Brinell hardness test. The experimental results revealed that the tensile strength of the composite with the addition of 5wt%-SiC nanoprticles could be increased to 215 MPa, increasing by 110% compared with pure Al matrix. Comparative experiments reflected that the-SiC nanoprticles showed significant reinforcement effect than traditional-SiC micro-sized particles. The preparation process and sintering procedure were investigated to develop a cost effective preparation strategy to fabricate nano-SiCp/Al composite.WANG Linong WU Hao WU Xingping CHEN Minghai LIU Ning 2013Journal of Wuhan University of Technology(Materials Science)2013,28,6:5
5Synthesis,insecticidal and acaricidal activities of novel 2-arylpyrroles显示文摘To search for novel 2-arylpyrroles with unique biological activities,a series of novel 2-arylpyrrole derivatives were designed and synthesized,and their structures were characterized by 1 H and 13 C NMR spectroscopy,MS spectrometry,and elemental analysis.Their insecticidal activities against Lepidopteran pests (e.g.Mythimna separata) and acaricidal activities against mites (e.g.Tetranychus urticae) were evaluated.The results of bioassays indicate that some of these title compounds exhibited excellent insecticidal and acaricidal activities.For example,4-bromo-1-((chloromethoxy)methyl)-2-(4-chloro phenyl)-5-(trifluoromethyl)pyrrole-3-carbonitrile (6a),4-bromo-2-(4-chlorophenyl)-1-((2-fluoroethoxy)-methyl)-5-(trifluoromethyl)pyrrole-3-carbonitrile (6d) showed insecticidal activity against Mythimna separata and 4-bromo-2-(4-chlorophenyl)1-((isopropoxymethoxy)methyl)-5-(trifluoro methyl)pyrrole-3-carbonitrile (7d) showed acaricidal activity against Tetranychus urticae.They were more effective than Chlorfenapyr,which has been the only commercialized member of a new class of chemicals of 2-arylpyrroles.LIU AiPing TANG Ming YU ShuYing LIU XingPing WANG XiaoGuang PEI Hui WU DaoXin HU Li OU XiaoMing HUANG MingZhi 2013Science China Chemistry2013,56,1:5
6Applicability and Prospect of China's Development Zone Model in Africa显示文摘Development zones have been an important spatial approach to promoting economic development since China's reform and opening-up. They have also been major contributors to the processes of China's industrialization and urbanization. Along with improvements in the worldwide industrial division of labor and the gradual implementation of China's development zones' Go Global strategy, it is necessary for Africa, a hot spot of global industrialization in recent years, to learn from China's development zone model. By attracting China's capital, technology and enterprises to Africa via Sino-African co-built development zones, a pattern of high complementarity and mutual development between China and Africa can be formed which does favor further improvement of the global industrial division of labor. In order to study the applicability and prospect of China's development zone model in Africa as per the above-mentioned international situation, this paper first sorts out the development course of China's development zones and discusses their roles in China's industrialization and urbanization. Subsequently, this paper analyzes the status quo of industrial development in Africa as a whole and the differences in industrial development between China and Africa, aiming to justify the timing of industrial transfer from China to Africa by constructing Sino-African co-built development zones. Lastly, this paper analyzes the current situation of six Sino-African co-built development zones by focusing on their operation modes, industry types and investment promotion models. In the authors' view, Sino-African co-built development zones can function as a new window of China-African cooperation, a new carrier of African industrialization, and a new engine of global industrial restructuring. China should adhere to the general principles of ‘Sino-African Integration, Multi-Cooperation, Mutual Benefit, Scientific Location, Systematic Planning, Cluster Growth and Open Development' in the planning and construction of development zones in Africa, effectively promoting Africa as the very important part of the global industry system.WANG Xingping ZHU Kai LI Yingcheng XU Jiabo 2017Chinese Geographical Science2017,27,6:2
7Research on the Development of China’s International Cooperation Parks Along the Belt and Road: Status Quo, Effect, and Trend显示文摘This paper predicts the future development trend of China’s International Cooperation Parks(ICPs) along the Belt and Road by systematically summarizing the current situation and the effect they exert.Relevant research shows that these ICPs have not only promoted China’s industrial capacity cooperation and international industrial transfer, but also contributed to resource sharing between China and the countries along the Belt and Road.In addition, the ICPs play a positive role in further advancing social development of host countries and bilateral cooperation.Research also indicates that the development of ICPs, influenced by both a Chinese domestic 'pushing force' and a foreign 'pulling force,' is a result jointly produced by political, economic, diplomatic, and cultural factors.As ICPs are built in increasingly more countries along the Belt and Road and their leading industries tend to be more diverse, the environment and infrastructure in host countries would be improved and the importance of Chinese private enterprises would be further enhanced.In addition, ICPs will also further promote the development of local industrial parks.What should also be noted is that problems like an unbalanced layout, irrational planning, and lack of planning standards still exist in the ICPs, thus solutions and strategies for resolving these problems are proposed in the paper.Zhao Shengbo Wang Xingping Hu Xuefeng Li Min(译) 2019China City Planning Review2019,28,2:2
8CFD simulation study of the effect of baffles on the fluidized bed for hydrogenation of silicon tetrachloride显示文摘In this study,the effect of channel baffles and louver baffles on the flow pattern in the large-scale industrial fluidized beds was studied by computational fluid dynamics(CFD)methods.Then,the effect of flow pattern on the chemical reaction performance was studied for the first time.Simulation results showed that the gas velocity distributed more uniformly,solid particles dispersed more homogeneously and aggregation scarcely occurred in the fluidized bed with louver baffles than that with channel baffles.The residence time distribution indicated that louver baffles remarkably suppressed gas back-mixing in comparison with channel baffles.The reasonable agreements of pressure distribution and reaction results between the simulation in the bed with channel baffles and the data on a large-scale industrial apparatus demonstrated the accuracy of the CFD model.The predicted conversion of SiCl_(4) in the bed with louver baffles(27.44%)was higher than that with channel baffles(22.69%),indicating that louver baffles markedly improved the performance of the fluidized bed.This study could provide useful information for future structural improvements of baffles in large-scale fluidized beds.Ning Liu Xingping Liu Fumin Wang Feng Xin Mingshuai Sun Yi Zhai Xubin Zhang 2022Chinese Journal of Chemical Engineering2022,35,5:2
9Structural and photoluminescent properties of ZnO films deposited by radio frequency reactive sputtering显示文摘Zinc oxide films with c-axis preferred orientation were deposited on silicon (100) substrates by radio frequency (RF) reactive sputtering. The properties of the sam- ples were characterized by X-ray diffractometer, X-ray photoelectron spectroscopy and fluorescent-spectrophotometer. The effect of sputtering power and substrate temperature on the structural and photoluminescent (PL) properties of the ZnO films was investigated. The results indicated that when the sputtering power is 100 W and the substrate temperature is 300-400℃, it is suitable for the growth of high c-axis orientation and small strain ZnO films. A violet peak at about 380 nm and a blue band at about 430 nm were observed in the room temperature photolumines- cence spectra, and the origin of blue emission was investigated.PENG XingPing WANG ZhiGuang SONG Yin JI Tao ZANG Hang YANG YingHu JIN YunFan 2007Science China(Physics,Mechanics & Astronomy)2007,50,3:1
